Electric Bikes - Do controllers have overheat protection?? Re: Cyclone controller

I would like to know if controllers in general have overheat protection where they shut down & specifically whether or not a CYCLONE controller has it. I have a complete new Cyclone system--a 650 watt & the controller is remote to where I cannot feel it while riding. On one of my 1st test runs I had just climbed a steep bridge (I had climbed it earlier & was on the return trip & some time had elapsed--1/2 hour or so) came down the slope and traveled a few blocks & the system shut down. I never saw a yellow light but may have missed it. When it stopped I turned the throttle wide open & got a red light so I pedaled home. @ the I was thinking the batteries were low so I put the charger on & much to my surprise the batteries were fully charged w/ 1-1/2 hours!!! (I did not think to feel the controller at the time---if it happens again I will) The other day, from a yellow light condition, I charged the batteries to full charge & that took 4 hrs. I have a 24 volt 6 amphr charger & am charging 2-24 volt 66 amphr SLA batteries for a total 66 amphrs @ 24 volts.
The next time I have a full charge I am going to take a voltage reading & the same when they are discharged to the yellow condition for reference.
I have felt the controller after a flat road ride & it is hardly even warm.
Any information and/ or comments would be greatly appreciated.

Personally I don't know if your controller has an over heat protection but I really don't think that was your problem anyway. You didn't say if you ever got power back again or not. I have had power failures on my Cyclone as well but I have the internal controller (never will buy that again). Like you I would get the red light for no reason and no power so I would start peddling home. But suddenly I would get full control again like nothing ever happened. But it would only last a few miles and go dead again. But when I got home it was fine again. This has happened a few times and I have never found the problem but I think it's in my brake wiring. Bottom line I bought a new ebike and haven't ridden the problem bike since the last time it fail. But I do plan to solve it this summer...... Check your brake wires and if possible jumper them out and test the bike.
Dumdass, thanks for the tips and yes, after I charged it the power was back on but @ this point I am not positive of the cause of failure because @ the time I thought it was low charge & so put the charger on it immediately & in 1-1/2 hrs it was charged---too short a time for complete battery drain---I had not thought to just let it cool for a while & try the power---I am learning!
In another forum I was told for fact the motor has overheat protection sensors & from the way the response was worded I think the controller itself may have them. Although the trike climbs the bridges fine in higher gears I am going to try the ridges in low low gear to make the climb easier on the system.
